Custos partnered with a leading ebook publisher to provide a new and innovative way to protect ebooks against piracy with watermarking technology that doesn’t affect honest users.

This unique system turns the downloaders of ebook files against the uploaders by leveraging a valuable Bitcoin bounty in every copy of an ebook sold or send to marketers or reviewers before release. The embedded bounties can be claimed from anywhere in the world by a network of “bounty hunters” using a free extraction tool thus enabling rapid detection of compromised material.
